Esztár, in Hajdú-Bihar county, is reported at 40.9 mg/L as CaCO3 in the 2024 NNGYK data, which is soft and well below most settlements in this batch. The entry does not explain why, and we do not offer a geological reason. Limescale should be minor, so a softener is unlikely to be needed.
Hungarian suppliers report total hardness in German degrees (nk°) or mg/L CaO; the limit is 50–350 mg/L CaO.
